Objective To investigate the relationship between disease activity and osteocalcin,β-isomerized C-terminal telopeptides (β-CTX) in SAPHO syndrome.Methods We studied 58 cases who were diagnosed as SAPHO syndrome.The following indices used to assess the activity of SAPHO were measured:Bath ankylosing spondylitis Disease activity index (BASDAI),Bath ankylosing spondylitis functional index(BASFI),visual analogue scale (VAS) pain and erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),osteocalcin and β-CTX.The SAPHO patients were divided from two groups according to the disease activity.The relationships were analyzed with t-test and Pearson's test.Results The β-CTX of the active group(0.43±0.20) ng/ml was elevated than the stable group (0.23 ±0.09) ng/mL (t=-4.620,P=0.007).And there was no significant difference in the osteocalcin between the active group (2.7±1.0) μg/L and the stable group(2.4±1.0) μg/L (t=-1.169,P=0.820).There was no significant correlation between the serum osteocalcin and ESR or hypersensitive CRP (hs-CRP) (rESR=0.228,PESR=0.088;rhsCRP=-0.085,PhsCRP=0.528).And β-CTX level was related to the VAS (r=0.496,P<0.01),BASDAI (r=0.401,P=0.002) and BASFI (r=0.295,P=0.025).While no significant relationship between the osteocalcin and pain index was observed in our study.Conclusion The positive correlation between serum β-CTX and disease activity indicates significant bone absorption during the bone destroy process in SAPHO syndrome.

OBJECTIVE:
To explore the conversion of resin monomer, the change of inorganic component and the influencing factors on the oxygen inhibition layer formed on the cured surface of resin cement.
METHODS:
Three kinds of resin cement were divided into three groups: (1) light-cured group: RelyX Veneer, NX3 (light-cured), Variolink N; (2) dual-cured group: RelyX U200 Automix, NX3 (dual-cured), Multilink Speed; (3) chemically-cured group, and the above 3 types of dual-cured resin cement cured without illumination could be used as chemically-cured resin cement. Each sample was provided with and without oxygen exposure of two matching surfaces, cured respectively, and the variables of light intensity and illumination time were set in the light-cured group and the dual-cured group. Scanning electron microscopy was used to observe the samples' surface morphology. Energy dispersive spectrometer was used to analyze the samples' composition of surface elements. Confocal Raman spectroscopy was used to measure the monomer conversion of resin cement and to obtain the thickness of the oxygen inhibition layer.
RESULTS:
(1) On the surface of cured resin cement, the weight percentage of oxygen element in the aerobic side was higher than that in the anaerobic side (P < 0.05), and the weight percentage of inorganic element was lower than that in the anaerobic side (P < 0.05). (2) The surface monomer conversion of the cured resin cement on the aerobic surface was significantly lower than that on the anaerobic surface (P < 0.05), and the surface monomer conversion on the aerobic surface and the anaerobic surface was the lowest in the chemically-cured group (P < 0.05), the dual-cured group was the highest (P < 0.05), and the light-cured group was between them. With the increase of light intensity or illumination time, the surface monomer conversion increased (P < 0.05). (3) The thickness of the oxygen inhibition layer was the thickest in the chemically-cured group [(40.27±2.81) μm](P < 0.05), the thinnest in the dual-cured group [(21.87±5.42) μm](P < 0.05) and light-cured group [(23.73±3.84) μm] was between them. With the increase of light intensity or illumination time, the thickness of the oxygen inhibition layer of resin cement decreased (P < 0.05).
CONCLUSION
When resin cement is exposed to oxygen, it will form an oxygen inhibition layer, its surface's inorganic filler is less, the surface monomer conversion is lower. The surface monomer conversion and the thickness of oxygen inhibition layer are affected by curing mode and illumination factors.

Objective To investigate whether the proportions of Th17/Treg balance were impaired in the peripheral blood of patients in different phases of synovitis acne pustulosis hyperostosis osteitis (SAPHO) syndrome.Methods We studied 22 cases diagnosed as SAPHO syndrome and 11 healthy controls.According to the scores of VAS pain,BASDAI and BASFA,the 22 patients were divided into active group and stable group.By means of flow-cytometry,the frequencies of total and different subsets of Th17 and Treg cells in peripheral blood mononuclear cell of different groups of SAPHO syndrome and healthy controls were studied.The values of Th17/Treg balance were analyzed.The relationship was analyzed with Kruskal-Wallis test,Mann-Whitney test and Pearman's test.Results The mean percentage of Th17 cells was markedly higher in the active group [(2.74±0.25)%] than in the stable group [(1.16±0.09)%] (U=0.000,P<0.01) and healthy controls [(1.13±0.11)%] (U=0.000,P<0.01).No differences were found among active group [(2.10±0.20)%],stable group [(2.51±0.20)%] and control group [(2.44±0.22)%] (x2=2.16,P=0.339 4).The ratio of Th17 cells to Treg cells was markedly higher in active group [(1.48±0.25)%] than in the other two groups [(0.47±0.03)%] (U=0.000,P<0.01).We also found the positive correlation of the ratios of Th17/Treg cells with the values of VAS in SAPHO syndrome patients (r=0.752 7,P<0.01).Conclusion The results demonstrate that the development of SAPHO syndrome is closely related to the imbalance of systemic Th17/Treg cells,Increased ratio of Th17/Treg cells may be the main factor that cause disease recurrence,and then,lead to the manifestations of high levels of inflammation and joint pain.
